ClassNotFoundException:org.apache.xml.serialize.XMLSerializer

問題

隨著Spring OXM+ Castor資料系結，Castor庫新增，但仍出現以下錯誤訊息？

Exception in thread "main" java.lang.RuntimeException: 
	Could not instantiate serializer org.apache.xml.serialize.XMLSerializer: 
	java.lang.ClassNotFoundException: org.apache.xml.serialize.XMLSerializer
	at org.exolab.castor.xml.XercesSerializer.<init>(XercesSerializer.java:50)
	//...

Castor 依賴於Maven。

<dependency>
		<groupId>org.codehaus.castor</groupId>
		<artifactId>castor</artifactId>
		<version>1.2</version>
	</dependency>

解決

如果要糾正這個錯誤，Castor 需要Xerces 工作，所以，也需要新增Xerces的依賴。
